There are various kinds of resins and each type comes in different formulations. KastEZ is a popular polyurethane resin formula that is commonly preferred by artists for their casting works.
Resins come in different types – polyester, epoxy and polyurethanes are the commonly used ones for making castings.
Of these, polyester resin is considered the most easy to use and the price is also reasonable. It cures to a hard form too. However, it emits noxious fumes which are quite dangerous for the user. Epoxy resin is also considered easy to use and is advised for beginners, primarily because of the longer pot time. It is safe to use, but cures soft which can make it difficult to handle.
It goes without saying that polyurethane resin is the most popular resin, even despite the comparatively higher price.
What works for polyurethane resin is that it is versatile and boasts of excellent strength, durability, elasticity and resistance to oils and other chemicals. It captures details well and generally cures to a hard form. However, varying the formulation of the resin can yield varying properties from a soft pliable rubber to a very hard and rigid plastic. It comes in both opaque and water clear forms to suit different applications. The resin is commonly preferred for general mold making and casting. Some of the polyurethanes may require the use of a respirator due to a mildly noxious odor.
The EnvironMolds MoldQuik is an example of a pliable polyurethane whereas KastEZ Resin cures to form an opaque, hard plastic casting.

The latter is a two-part polyurethane casting resin used in 1 to 1 ratio by volume. It is available in 16 oz, 2 quarts and 2 gallons packaging. Initially, when both the catalyst and base are added together, the resin will look cloudy. It will begin to clear with the mixing. A thorough mixing while properly scraping the sides and bottom will cause the resin to become clear and this is when it is ready to use.
KastEZ resin is easy to use. Simply pour the resin into the mold and allow it to set. It cures at room temperature – within 10 minutes itself. A release agent is required, but demolding is a straightforward process as well.
The cast will be lightweight and will form a hard plastic with an ivory white color. Special resin dyes have to be used to impart a specific color to the resin. The colorant can be easily mixed into the resin to get the desired color. Proper mixing will give a uniform color while a few strokes will create a marbleized effect. The dye will not affect the pot life, demold time or even the inherent properties of the cured plastic in any manner.
This same resin can in fact be cast in both rigid and flexible molds. Some of the most common uses are figurines, displays, rapid prototypes, special effects and sculpture reproductions. In fact, KastEZ polyurethane resin is the right choice for almost any application.
